It will further be seen that with the construction described I have provided a compact vaporizer and Water freezing unit without an increase in overall dimension ordecrease in air cooling efliciency.

Various changes can be made in the details of construction described herein withchamber, and a removable water containe within said freezing chamber.

2. In mechanical refrigerating apparatus,

' a cooling unit comprising a vaporizer containing volatile liquid refrigerant, a freezing chan'iber arranged interior-1y of said vapor-- izer and accessible from the exterior of said vaporizer, heat absorbing means entirely enclosed intermediate said chamber and the refrigerant in said vaporizer, and a removable container in said freezing chamber.

3. in mechanical refrigerating apparatus, a cooling unit comprisinga vaporizer containing a volatile liquid rei fiigerant, a charm ber arranged interiorly or said vaporizer and accessible through an opening in a wall thereof, heat absorbing means intermediate said'chamber and the refrigerant in said vaporizer, anda container in said chamber removable through the opening in the Wall of said vaporizer, said container being provided with an end plate for closing the opening in the wall of said vaporizer when inserted in the chamber.

4;. Inmechanical refrigerating apparatus, a cooling unit comprising agvaporizer for containing volatile liquid refrigerant, a pair of spaced shells secured to a 'Wall of said vaporizer, the space intermediate said shells being substantially filled with brine and the space interior'of the inner shell forming a storage chamber, said vaporizer Wall and inner shell having registering openings, and a slidable container for saidstorage chamber.

5. In a mechanical refrigerating apparatus, a cooling unit comprising a, vaporizer casing for containing liquid refrigerant, said casing having an opening in a Wall thereof, a lcakproof storage chamber extending interiorly of said casing from the opening in the wall, a closed brine containing chamber surrounding said storage chamber and substantially surrounding said storage chamber, and removable means for closing the opening in the wall of said vaporizer easing.

In testimony whereof, I hereunto affix my siguatnre.
